"With standard and heavy duty foil, it's perfectly fine to place your food on either side so you can decide if you prefer to have the shiny or dull side facing out," according to the Reynold's website.
The shiny side of aluminium foil for cooking food is supposed to be down. Namely, you should have the less shinier said to get contact with food, otherwise food may get stuck on the foil surface during baking, especailly meat.
The non-stick side is the side with the dull or flat finish. To help indicate which side is non-stick the foil has been imprinted with the words "NON-STICK Side."
Though there is a difference in how much heat the shiny vs. dull side reflects or retains, measured over time and considering the type of heat the oven emits, that difference is negligible and has little to no discernable impact on the food. That's why it doesn't matter which side you use.
Tin foil is stiffer than aluminum foil. It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminum and other materials for wrapping food.
Both sides have the same properties. The difference in terms of appearance is only due to the manufacturing process. (Two foils are laminated at the same time, so each foil is in contact with the rolls on one side only — hence the asymmetrical look).
Coating the dull side of aluminum foil with oil or cooking spray forms a protective barrier, preventing food from sticking and ensuring hassle-free cooking.
Parchment paper, on the other hand, has a heat-resistant nonstick coating, so it's safe for use in the oven. The parchmenting process makes the paper greaseproof, durable and heat- and moisture-resistant, too.
With standard and heavy duty foil, it's perfectly fine to place your food on either side so you can decide if you prefer to have the shiny or dull side facing out. For Reynolds Wrap® Non-Stick Aluminum Foil, you'll want to have the dull side facing up.
In that case, the dull/matte side is the food contact side.
Shiny side up. Your vehicle hasn't flipped over after a rollover or accident. “Keep the shiny side up” means to have a safe trip.
I agree with previous answer as the shiny and not shiny part has the same heat conductivity and it does not mean one side had been oxidized more than the other. The difference in shininess is simply a result of manufacturing process.
Does It Matter Which Side of the Aluminum Foil You Use? The short answer is no. Since the matte and gloss are a result of the foil's contact with the roller, Tiro asserts that there is no difference in the material make-up of both sides of the foil.
If you're baking fish, roasting vegetables or preparing a piece of meat for dinner tonight, chances are that you'll wrap your food in aluminium foil. What you may not realise is that some of the foil will leach into your meal – and this could be bad for your health.
Spray the foil with PAM Cooking Spray before you add in the contents.
Quite simply, it doesn't matter what side of aluminum folk you use. Either is acceptable. Since the exact same material makes up both sides, they will perform precisely the same way. The only difference is aesthetic.

The term "tin foil" survives in the English language as a term for the newer aluminium foil. Tin foil is less malleable than aluminium foil and tends to give a slight tin taste to food wrapped in it. Tin foil has been supplanted by aluminium and other materials for wrapping food.
Do not ever use parchment or wax paper in the broiler. Despite its heat resistance, parchment paper can't handle the heat of any broiler, which can reach temperatures upward of 500°F. And wax paper? It should never come near the high heat of the oven or broiler.

When shouldn't you use parchment paper? Parchment paper is not meant for high-heat cooking. The product box should indicate the highest temperature it can safely withstand, which is usually around 500℉. Do not use parchment paper when grilling or otherwise near an open flame.
